IMPROVEMENT IN BIRD-CAGES.

SPECIFICATION.

- We, GEORGE R. OSBORN and BnNJ. A. DRAYTON, of the town of Morrisania, Westchester county, New York, have invented certain Improvements in Bird-Gages, of which the following is a specification:

The nature and objects of the invention in general are in continuation of a series of improvements being made by us in the construction of bird-cages without the use of solder as a means of fastening the different parts together, at the same time increasing strength and durability, giving an ornamental appear- I ance to the structure, and lessening cost of production. This particular case refers to the main fastenings of filling-wires and framework, and is in itself a new system of con- "struction of bird-cages. 1

Description of Drawing.

Figure 1, side elevation of the body of the cage, the door and cup-rests not being represented, as not being pertinent to the invention; Fig. 2, top elevation of upper section of the body of the cage cut-on dotted line F Fig. 3, section of filling-wire; Fig. 4, section of the crimped spring distendin g and adjusting framering; Fig. 5, section of filling-wire with sectional view of frame-rings cut at point of contact, illustrating a transposition of parts and forms, as hereinafter specified.

. By Letters.

A, grooved metal ring, in which the upper ends of the filling-wires G" are inserted and soldered in place; B, large wire drilled at reg- F ular and suitable distances for the insertion of the lower ends of thefilling-wire G", which are also soldered in place; 0", filling-wires of the cage; notched, indented, or crimped in such a manner as to form three seats or angles, a. b a, at two points in their length, for giving position to the- D D, crimped distending-ring, which, being,

There are represented. two sets of frame specified.

rings. Any number of sets may be used, according to the height of cage or strength of structure required. The upper and lower ends of the filling-wires being in such position that the solder used is not noticeable they are soldered for the sake of firmness. The intermediate fastenings, consisting of three rings, as above described, have all requisite firmness, and the elasticity of the cage is an advantage, as in case of concussion in falling or careless handling there is less danger of breakage or of bending the wires than where all fastenin gs are positive. i

The order of the crimped distending-ring D and hoop or binding-rings E, Fig. 5, may be transposed, and order of crimping in fillingwires O reversed, giving in the system. two

. crimped distendin g-rin gs and one binding-rin g, the result remaining the same-t. 0., the crimp form of the distending ring or rings D, in combination with the crimps in the filling-wires G", gives position each to the other, and is bound in place by the hoop or binding-rings or ring E.

The distending-ring D may be a notched strip of plain or folded sheet metal. We have chosen wire as best in effect and appearance.

We 'do not claim as new the use of the crimped distending-ring D simply, nor of it in combination with the crimp in filling-wires O as that arrangement is allowed us by Letters Patent No. 114,593, of May 1, 1871, nor of the method of positive fastening of the upper and lower ends of the filling-wires O", as hereinbefore specified; but

What we claim as new, and of our invention, is-- In the frame-work of a bird-cage, the combination of the crimped filling-wires 0 and crimped distending ring or rings D, each giving position to the other, with the hoop or binding rings or ring E, holding the fillingwires 0" and distending ring or rings D in position, substantially as and for the purpose GEORGE E. OSBORN.
